I have bearded dragons, green anoles and had an iguana. Of the three I would suggest the bearded dragons. They are more expensive than the other two, but well worth the investment. They eat a wide variety of insects, fruits and vegatables. Sassfrass sent me a very extensive food list for them. They are docile and great with my kids (9, 8 and 5 yrs old). They even seem to thrive on human contact. They seem to be pretty easy to care for. Green anoles are fun to watch but do not like being held, both of mine bit the guy at the pet store. Iguanas are the cutest little green monsters you will ever see, and not what you need at all. They are very antosocial and hard to care for. I really like the bearded dragons, just keep in mind they will require something larger than a 10 or even 20 Gallon tank.
